Authorities say the vehicle in question would have a discoloration on the front bumper. Heckler provided this photo to demonstrate the look of the vehicle authorities are seeking.

Canazaro, 48, was killed Jan. 18, when two men barged into his home in 300 block of Swartley Road in an upscale neighborhood. Canazaro's live-in girlfriend and her son were tied up, but left unharmed, authorities said.

Police said the two men fled Canazaro's home in his 2007 black Lincoln pickup truck, which was later found abandoned at a Friendly's restaurant at 1465 West Broad St. in Quakertown.

Heckler urged anyone with information about the vehicle to contact Bucks County investigators at 215-453-6011.
